Coronary lesion physiological assessment and imaging


Coronary lesion physiological assessment and imaging (FFR, IVUS, OCT)
Manipal Hospitals’ Cardiac Unit boasts of futuristic diagnostic and testing machinery that combines advanced technology and high precision tools to present the most complex of cases with accuracy. Typical cardiac tests reveal the extent of the damage done to the coronary arteries, helping our cardiologists to plan the appropriate and most effective treatment.

Fractional Flow Reserve (FFR)

Fractional Flow Reserve (FFR) is a guide wire-based process that precisely measures blood pressure and how freely the blood flow is through a specific part of your coronary artery. Based on the readings where the speed of the blood flow can indicate blockages, cardiologists can decide on the best option between angioplasty or stenting, or plain medications. 

Intravascular Ultra Sound (IVUS). 
This test is performed in the Cath lab, or even non-invasive Multislice CT scans. Here, very high frequency sound waves, called ultrasound, are emitted by a transducer. These are beyond the range of human hearing and bounce off the various types of tissue structures in the body. These echoes are converted into a picture. The cross-section view of the images help interventional cardiologists in stent sizing, and to ascertain if the stent has been placed optimally, is fully expanded and enclosed within the vessel wall.

Optical Coherence Tomography (OCT)

Optical Coherence Tomography (OCT) uses infrared light to make a detailed evaluation of coronary atherosclerotic plaques and of the vascular response to coronary interventional devices, such as new generation coronary stents. Optical coherence tomography can also be used as a guide for coronary intervention.
